摘要： Method of producing variety of golf club shafts from universal blank shaft of given length includes steps of determining actual natural frequency of blank shaft. Selected amounts of shaft length are then removed from both tip and butt end portions of blank in correlation with natural frequency of blank. Total amount removed from blank solely depends upon length of shaft desired while selected amounts removed from tip and butt end portions of blank solely depend upon natural frequency of shaft desired. As proportional amount removed from tip portion increases, frequency of produced shaft also increases. Conversely, as proportional amount removed from tip portion decreases, frequency of produced shaft also decreases.

摘要： Method of producing matched golf clubs comprises steps of determining under similar conditions frequency of each golf club shaft of plurality of shafts. Shafts are selected from plurality such that frequencies thereof fall on predetermined gradient formed by plot of shaft frequency and shaft length. Frequency increments between successive shaft lengths along gradient are substantially equal. Subsequent mating of shafts with selected club heads produces integrated and correlated matched golf clubs. Matched set of shafts and clubs is also described.
摘要翻译：制造匹配的高尔夫球杆的方法包括在类似的条件下确定多个轴的每个高尔夫球杆杆的频率的步骤。轴选自多个，使得其频率落在由轴频率和轴长度的绘图形成的预定梯度上。沿梯度的连续轴长度之间的频率增量基本相等。随后与选定的球杆头配合的轴产生集成和相关的匹配的高尔夫球杆。还描述了一组轴和球杆。
